IT MOSTLY depends on if you have 30k to spend on a motor ... anyone with that kind of money can get 700 hp with everything right out of the box ... everyday of the week. Most of us have a budget. I will guarantee Edelbrock has done their market research and found 90% of the cleavor builds will need a set of middle of the road heads at a budgetary price.
Most people have a budget and feel where will I need 700 hp for the street.
The other 5 % of the people buy parts on a search for a good deal with a specific horsepower range in mind ( example we dont need a block for 2000 hp when your going to make 650hp.) You can but NEW race parts everywhere at a good deal.
There are CLEVORS making 1400hp with C302B heads.
It all depneds on budget ... and if your going to enter the MASTERS Competition ?
